Cannot paste multiple lines into integrated terminal

Hi, I have multiple lines of code that I want to paste into my PyCharm terminal, but after each line it treats it as a return. This is annoying as I am running a python repl in my terminal and I would like it to be able to paste a function instead of writing it out. See attached gif

The same issue is there with the IntelliJ terminal, so I'm thinking it has something to do with how the integrated terminal is setup.
